There are a few nice Rockets painted in a flat, primer-gray camo scheme that look really, really cool (IMHO). If you go to the Team Rocket "builder's albums" site
here, look for Tom Martin's album, and the Team Rocket EVO album. Both are great looking airplanes, and are light gray on medium gray camo. The Team Rocket EVO plane is the cover bird.
Tom told me, when I was whining about making speed mods and messing up my nice paint job, that I shoulda gone with primer gray camo, and I'd be able to make all the mods I want, and not worry about the paint. To be honest, if I was painting one now, that's
exactly what I would do! Not just for the mods...it looks awesome.
Not sure on cleanup, but those airplanes seem to look good, in pics and in person. As far as vis goes, if you're not always flying over gray water, or under gray skies, or off of gray boats

...I think it'd be OK. You can always add a big R,W& B Flag, a big red star, or some other design (EDIT: Ooohh, or a big red bulldog...just saw you are from Fresno...my condolences, I'm a SJSU guy!

). For hi vis, look at Wayne Hadath's album on the Team Rocket site...black and gray primer, and easy to see. Both his and Tom's actually are fairly easy to see. Unfortunately, I always seem to be looking at them from the rear quarter...not necessarily a bad thing from a fighter pilot's perspective

...I just wish I could make them get bigger in the windscreen

. They are really fast...maybe its that primer paint!
Ya know, glossy ain't bad either...saw the gent's that was paited like a Corsair last year too...very nice, and it'd be another fun way to go!
Have fun with the paint...fun to start with a blank sheet!
Cheers,
Bob
